CCI's Clean-22 rewrites the rules on rimfire fouling... an exclusive red polymer coating on the 40-grain lead round nose bullet keeps copper and lead buildup out of your barrel without leaving residue behind. That same coating slashes suppressor fouling by 60 to 80 percent, while optimized bullet geometry and dependable CCI priming keep cycling smooth through semi-autos and every other .22 LR platform. It's a clean-shooting, reliable choice for casual range days or serious competition volume.
